I spent the last two weeks of July and the first week in August overseas. My HH was stored outside, and it was HOT here.
 
Got home, stuck in the key, and it started right up. And the charge level indicator showed probably 80%...
 
So what you are experiencing makes no sense to me... Anyone have any other experiences to report?

Thanks. This makes me very sad. I live in fear now of puncturing it again. Apparently the 2008s have been redesigned to protect the condenser. Oh, well, I should never have bought a first model year.

That's nonsense. I've had two problems like that with my 2004 Prius in 4 years. I must have left a light or something else on. I've gone as much as two months without using the car with no problem upon returning. Get a new dealer.

To solve this problem find a new dealer. The dealer is giving you totally incorrect information. The battery does not go dead after 7 days of inactivity. Your battery should be good for much greater than than 8 weeks of inactivity.
 
Toyota recommends running the vehicle for at least 30 minutes after 8 weeks of inactivity to recharge the small auxiliary battery and the main HV battery. (Toyota Technical Service bulletin #PD0116-05).
 
Your dead battery is most likely due to a door left slightly ajar or some accessory or interior light left on which will run down the small aux battery until dead.
 
This already happened to me once when I left one of the back passenger doors slightly ajar in my garage while away for 4 days. When I came home the vehicle was dead as the interior dome light stays on forever if a door is ajar while the vehicle is off. Note that the main HV battery is not dead - just the small aux 12 volt battery. However, the car will not start if the aux battery is discharged.

which battery? The 12v can run down just like any other for the same reasons.

Add running boards to HH by sxnhe

Hello, I would like to add running boards to my 06 HH. Has any body installed them on your HH by a Toyota dealer? From another hybrid vehicle forum, I learnt that there might be a problem with the high voltage cable inside the rocker panel.

bumper guards by rgeismar

I am looking for a front and or rear bumper guard for my 2006 HH. I am most interested in a WAAG for both practicality and an austere look. I live in New York City and my bumpers are getting really chewed up. WAAG makes both guards for the 2006 Highlander but refuses to say whether they will fit the hybrid. The toyota customer service refuses to comment on aftermarket stuff and my dealer will not answer either. Does anyone know from experience if the guards from the regular highlander fit the HH; both 2006 model years. I guess the question is: Is the undercarraige where it bolts on the same on both models. Thanks to all those who help with this and all other questions asked on this forum.

Hydro Lock??? by doug28
Nov 24, 2007 (5:15 pm)

Greetings Toyota owners.
 
I purchased my HH about April of '06 and it currently has 26,000 mile on it.
 
I will not bore you with the 10 page dicertaion of what all happened to my car but you are welcome to ask questions as you comment on this thread.
 
To put it in short form.
 
HH starts shaking. Owner has it towed to Toyota dealer. Dealer calls and says "Bad gas, not covered under warranty, $285.00" Owner says please fix it. Dealer runs & idles it for 2 days calls and says engine blown, steel parts fly out from under it. Calls in special tech for HH. 8 days later leaves message that cause was hydro lock not covered by warranty.
 
This looks bad for us. I must guess five to seven thousand for new engine.
 
On top of this they performed the 30,000 mile service prior to purgeing the gas.
 
Confused.

YES!!!! In fact I just came in from our dead Highlander to search online to see if other people were having this problem! We have had this happen repeatedly, have taken the car in to the dealer countless times, and after a lot of head-scratching they told us we had to drive it frequently, which seems counterintuitive to buying a hybrid to lessen one's impact. They've even replaced the battery once, thinking maybe it was defective, but it hasn't helped. If we can't drive it frequently, they told us we had to disconnect the negative battery terminal or put a battery charger on it.
 
What's really weird is that sometimes the battery is completely dead, like now. But there have been other times that it started right up, drove a substantial distance (120 miles), then wouldn't start again after it had been off an hour.
 
We use our Highlander infrequently because our main car is a Prius and we only use the Highlander when we need to pull a trailer when our band tours. We've already been stranded at a club in the middle of the night with a trailer full of expensive gear because the car didn't want to start (after having driven 40 miles with no problem).
 
This is very frustrating, especially now that it's completely dead and we have a trip Friday. We had to bring our tractor over to start it, but of course it turned itself off then died completely before we had a chance to put the tractor away. Does anyone have any thoughts on how to proceed? It does seem like a pretty big design flaw.
 
EDIT: Found this confirmation on the Toyota FAQ page…what a drag!
In addition to the storage tips for our conventionally-powered vehicles, our hybrids require additional steps for each battery, as the hybrid vehicle battery and auxiliary battery will discharge and their condition is liable to decline.
 
To prevent excessive auxiliary battery drainage, charge the battery at least once every two weeks by driving the vehicle for 15 - 20 minutes with all non-essential electrical accessories (such as air conditioning and audio equipment) turned off. As an alternative, you may disconnect the negative terminal of the auxiliary battery.
 
For the hybrid vehicle battery, charge the battery at least once every two months by starting the hybrid system for about 30 minutes*. Check that the "ready" light is on and all lights and electrical accessories are off. It is not necessary to drive the vehicle, but do not start the hybrid system in an enclosed area unless the tail pipe is connected to an exhaust hose to prevent harmful build up of fumes.
 
*If the battery was disconnected, it will have to be reconnected before the hybrid system is started.
